Description

Ecological slope protection structure of prefabricated assembled closed lattice beam

Technical Field

The utility model relates to an ecological slope protection structure of prefabricated assembled closed lattice beam is applicable to the side slope support construction in fields such as building, highway, town road, river course, is particularly useful for the side slope support construction that requires higher to the ecology.

Background

When the traditional side slope construction adopts lattice beam support, cast-in-place reinforced concrete is generally adopted. The cast-in-place construction has a plurality of problems: firstly, after the lattice beam reinforcing steel bars are installed, the concrete pouring time is longer, so that the construction period is long; secondly, the formwork is arranged on the slope of the side slope, the supporting difficulty is high, and the construction efficiency is low. When the concrete is poured and vibrated, the quality problems of untight vibration of the beam body, die running and the like easily occur. If the slump of the concrete is controlled improperly or the concrete vibrates excessively, the whole oblique beam can be collapsed, and great construction difficulty is brought to concrete construction; thirdly, a large number of workers are needed for binding the steel bars and pouring the concrete, and industrialization cannot be realized.

Therefore, it is especially important to develop a prefabricated assembly type superposed lattice beam ecological slope protection structure with high standardization degree, reliable quality, convenient construction, energy conservation, environmental protection, good ecological performance and high safety. The utility model discloses just develop under such background and form, be applied to and certainly will gain obvious economic benefits and social in the construction of actual lattice Liang Hupo.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an aim at to the construction period that cast-in-place lattice beam exists long, the template is erected and is established the degree of difficulty big, lattice beam concrete quality is difficult to guarantee, the low scheduling problem of industrialization degree, has provided a prefabricated assembled closed lattice beam ecological slope protection structure, this slope protection structure standardization level is high, the quality is reliable, the construction is convenient, energy-concerving and environment-protective, the ecology is good, the security is high.

In order to realize the technical purpose, the utility model adopts the following technical scheme:

the prefabricated superposed lattice beam ecological slope protection structure comprises a lattice beam; the lattice beam is formed by assembling prefabricated superposed beams; the prefabricated superposed beams comprise cross superposed beams, T-shaped superposed beams, L-shaped superposed beams and linear superposed beams, and superposed cavities are arranged in the prefabricated superposed beams; the cross-shaped superposed beam, the T-shaped superposed beam and the L-shaped superposed beam are arranged at the corner part of the lattice beam and are fixed on the slope surface through anchor rods; a linear superposed beam is arranged among the cross superposed beam, the T-shaped superposed beam and the L-shaped superposed beam in the longitudinal and transverse directions; the adjacent prefabricated superposed beams are mutually occluded through the tongue-and-groove and mutually pulled and combined through the reinforcement cage; and filling core concrete is arranged in the superposition cavity.

Adopt the technical scheme provided by the utility model, compare with prior art, have following beneficial effect:

(1) The standardization degree is high. The lattice beam is split into four prefabricated superposed beams, superposed beam components are standardized and uniformly arranged in the same category, factory fixed-point production and processing are adopted, and all links of processing, transportation, installation and the like of the prefabricated superposed beams are tightly combined, so that standardization, programming and industrialization of lattice beam construction are realized. The cross-shaped superposed beam, the T-shaped superposed beam and the L-shaped superposed beam are suitable for the Liang Zhuaijiao part of the lattice, and the straight-shaped superposed beam is suitable for the Liang Biaozhun part of the lattice, so that the cross-shaped superposed beam, the T-shaped superposed beam and the L-shaped superposed beam are convenient to install on site and do not need to cut a beam body.

(2) The quality is reliable. Prefabricated superposed beam component adopts the batch production prefabrication, and structural dimension is comparatively accurate, and during site operation, roof beam body group dress is controlled more easily, and it is whole to indulge transverse connection with the superposed beam through post-cast concrete, and the structure of lattice roof beam is firm, has reached "cast-in-place equally" effect, and then can effectively reduce rework and reprocess, practices thrift the cost. In addition, the problems of uncompacted vibration of the beam body, die running and the like are not easy to occur in the construction process, and the quality of concrete is ensured.

(3) The construction is convenient. The application of the lattice Liang Diege assembling process avoids a large amount of on-site formwork erecting operation, reduces a large amount of on-site wet operation, has less labor resource investment, obviously improves the mechanization degree, obviously reduces the labor intensity of operators and greatly improves the construction efficiency.

(4) Energy conservation and environmental protection. Compared with the traditional formwork technology, the wet operation of the superposed lattice beam construction site is less, so that the production of site concrete pouring and tamping and garbage sources is reduced, the emission of water, gas, sound, slag and dust in construction is effectively controlled, and the environment-friendly lattice beam formwork has obvious advantages in the aspect of environmental protection.

(5) The ecological performance is good. The adhering net is arranged in the lattice beam planting area, the adhering net can effectively adhere to planting base materials and prevent water and soil loss, and further the ecological effect of the lattice Liang Hupo is improved.

(6) The safety is high. By adopting the flow line construction mode of downwards finishing one layer of slope, namely downwards constructing one layer of lattice beam, the excavated slope can be protected in time, the problems of slope collapse and the like are effectively avoided, and the safety is higher.
